Vodacom has the worst service !!!

I have been trying for the past 2 weeks to get a simple letter from either the Collections department or customer services to say my account is up to date, I have spoken to Willona yesterday (after been cut odd many times and transferred to non existant departments) from collections who promised me that her manager will send the email letter in a hours time which never arrived, it is 8:50 the following day and I am asking Andile from Customer services who cannot help me and has put me on hold now for 30 mins, I asked to speak to his manager David Nyembe who refuses to take the call. all I ask for is a simple letter / email but no one from Vodacom cannot help me....this is the worst company and I want a personal apology from the CEO of the Company explaining to me in detail why is the service under him so pathetic accompanied with the up to date letter!!!
